In the precise process of aircraft manufacturing, fuselage stress testing is a key checkpoint to ensure flight safety. This test aims to accurately simulate the impact of constantly changing atmospheric conditions on the fuselage during flight, with the biggest challenge being the need to rapidly pressurize and exhaust large volumes of the fuselage.Proportion-AirWith its advanced electrical proportional valve technology, it provides an efficient and accurate solution for this complex testing, helping customers accelerate the process of product launch to the market.

In response to the customer's stress testing requirements for the aircraft body,Proportion-AirCarefully designed two regulator setting schemes. Among them, one4The inch pressure reducing valve is specifically responsible for controlling the inflation process of the aircraft body, while the other is4The inch back pressure valve is responsible for releasing pressure. These two large dome loading regulators are electronically controlled by the pilot operating the dome, making the entire pressure regulation process more flexible and precise.

In actual testing, this dual regulator setup demonstrated excellent performance. During the inflation phase,4The inch pressure reducing valve can quickly introduce a large amount of gas into the body, achieving rapid pressurization; During the exhaust phase,4The inch back pressure valve efficiently releases pressure, ensuring that the body can quickly return to its initial state and prepare for the next test. This fast and precise pressurization and exhaust capability greatly shortens the testing cycle and saves valuable time for customers.

BD6Back pressure top mounted regulator: the backbone of excellent performance

BD6The back pressure top mounted regulator is one of the core components in this solution. It adopts a unique dome loading back pressure design, achieving better performance than standard regulators by creating a cap shaped structure with a loading back pressure valve. The regulator is equipped with a diaphragm, which makes it far superior to piston regulators in terms of response speed and pressure or vacuum control accuracy.

In the stress test of the aircraft body,BD6The back pressure top mounted regulator exhibits extremely high accuracy and stability. Its accuracy depends on the pilot's operation, but thanks to its precise design and manufacturing process, it can ensure reliable pressure control under various working conditions. At the same time, it has a largeCVRating, controllable range within4to220Between them, it can meet the traffic requirements in different testing scenarios. In addition, its reduction ratio has reached1000:1When closed, it meets the requirementsANSI/FCI 70 - 3 6Class standards ensure the safety and reliability of pressure regulation. In terms of working temperature,BD6can-425to450 FWork normally within a wide range and adapt to various harsh testing environments.

QBXIndustrial electronic pressure regulator: the precise choice for closed-loop control

QBXIndustrial electronic pressure regulators, as closed-loop electronic pressure regulators, also play an important role in stress testing of aircraft bodies. It has a full vacuum to175The wide pressure range of pounds per square inch can meet the requirements of different pressure levels during testing. A wide range of analog and digital command signal options make it easy to integrate with various testing control systems, achieving precise pressure control command input. At the same time, the simulated monitoring output signal is used for data acquisition standards, which facilitates real-time monitoring of pressure changes by testing personnel and ensures the controllability of the testing process.

QBXThe precision and repeatability are one of its major highlights. Its accuracy reaches±0.2% F.S.The repeatability is±0.02%Full range, which means it can provide highly consistent pressure output in multiple repeated tests, ensuring the reliability and repeatability of test results. After close proximity10Billions of tests,QBXIt can be used stably for a long time almost without recalibration and maintenance, and its ease of use and long lifespan combined with a sturdy and durable structure make it stand out among similar products. In addition,Proportion-AirIt can also be customized according to the specific needs of customersQBXMake various modifications and provide customized solutions.
